34 Burning in a kiln

34 Burning in a kiln - formation of cement clinker The next step in the process is to heat the blended mixture of raw ingredients (the raw mix) to convert it into a granular material called cement clinker This requires maximum temperatures that are high enough to partially melt the raw mix.

roller press raw mill in cement

Traditionally, ball mills are used in cement industry for raw material, fuel and product grinding Ball mills use an established technology and offer certain advantag However, they have higher energy demands By using an appropriate kind of the more efficient roller mill technologies - either as a replacement or in combination with ball.
